I am trying to find out why the code below does not seem to work. It does not give an error - it simply doesn't scale. It actually does seem to work if I change it as to my second code sample. Anyone got any idea?
Thanks
public static void StartMouseEnterAnimation(Button button)
{
Storyboard storyboard = new Storyboard();
ScaleTransform scale = new ScaleTransform(1.0, 1.0, 1, 1);
button.RenderTransformOrigin = new Point(0.5, 0.5);
button.RenderTransform = scale;
DoubleAnimation growAnimation = new DoubleAnimation();
growAnimation.Duration = TimeSpan.FromMilliseconds(300);
growAnimation.From = 1;
growAnimation.To = 1.8;
storyboard.Children.Add(growAnimation);
Storyboard.SetTargetProperty(growAnimation, new PropertyPath(ScaleTransform.ScaleXProperty));
Storyboard.SetTarget(growAnimation, scale);
storyboard.Begin();
}
--- The following DOES work but I had to create a TransformGroup and reference this through a more complicated PropertyChain...
public static void StartMouseEnterAnimation(Button button)
{
Storyboard storyboard = new Storyboard();
ScaleTransform scale = new ScaleTransform(1.0, 1.0, 1, 1);
button.RenderTransformOrigin = new Point(0.5, 0.5);
TransformGroup myTransGroup = new TransformGroup();
myTransGroup.Children.Add(scale);
button.RenderTransform = myTransGroup;
DoubleAnimation growAnimation = new DoubleAnimation();
growAnimation.Duration = TimeSpan.FromMilliseconds(100);
//growAnimation.From = 1;
growAnimation.To = 1.1;
storyboard.Children.Add(growAnimation);
DependencyProperty[] propertyChain = new DependencyProperty[]
{
Button.RenderTransformProperty,
TransformGroup.ChildrenProperty,
ScaleTransform.ScaleXProperty
};
string thePath = "(0).(1)[0].(2)";
PropertyPath myPropertyPath = new PropertyPath(thePath, propertyChain);
Storyboard.SetTargetProperty(growAnimation, myPropertyPath);
Storyboard.SetTarget(growAnimation, button);
storyboard.Begin();
}
I was able to get it to work by tweaking your first code sample like so:
public static void StartMouseEnterAnimation(Button button) {
Storyboard storyboard = new Storyboard();
ScaleTransform scale = new ScaleTransform(1.0, 1.0);
button.RenderTransformOrigin = new Point(0.5, 0.5);
button.RenderTransform = scale;
DoubleAnimation growAnimation = new DoubleAnimation();
growAnimation.Duration = TimeSpan.FromMilliseconds(300);
growAnimation.From = 1;
growAnimation.To = 1.8;
storyboard.Children.Add(growAnimation);
Storyboard.SetTargetProperty(growAnimation, new PropertyPath("RenderTransform.ScaleX"));
Storyboard.SetTarget(growAnimation, button);
storyboard.Begin();
}
Instead of new PropertyPath(ScaleTransform.ScaleXProperty))
, I used new PropertyPath("RenderTransform.ScaleX"))
, and I set the target of the storyboard to the button (not the scaleTransform itself).
Hope that helps!
